Error details and causes
The setting value of the "[Da.6] Positioning address/
movement amount" exceeds "[Pr.13] Software stroke
limit lower limit value".
[Operation status at error occurrence]
At operation start: The system does not operate.
In the analysis of new current value: Current value is
not changed.
During operation:
• The system stops immediately when the positioning
address during position control (including position
control in speed-position switching control or position-
speed switching control) is switched to the data
outside the software stroke limit range.
• During speed control (including speed control in
speed-position switching control or position-speed
switching control), the system stops at the setting
(normal deceleration stop only) of sudden stop
selection (stop group 3) in the detailed parameter 2
when the current feed value or machine feed value
during manual control is outside the software stroke
limit range.
At speed control mode/torque control mode/continuous
operation to torque control mode: The system switches
to the position control mode and stops immediately
when the current feed value is outside the software
stroke limit range.
In the circular interpolation with sub points designated,
the sub point exceeds "[Pr.13] Software stroke limit
lower limit value".
[Operation status at error occurrence]
At operation start: The system does not start.
The control method sets an operation pattern
(continuous path control) using new current positioning
data.
[Operation status at error occurrence]
Current value is not changed.
The operation pattern sets a "new current value" in the
control method using the data following the "continuous
path control" positioning data.
[Operation status at error occurrence]
Current value is not changed.
"[Da.1] Operation pattern" is "Continuous positioning
control" or "Continuous path control" when "[Da.2]
Control method" is "Speed control" or "Position-speed
switching control".
[Operation status at error occurrence]
The system does not operate at start.
"[Da.1] Operation pattern" is "Continuous path control"
when "[Da.2] Control method" is "Fixed-feed" or
"Speed-position switching control".
[Operation status at error occurrence]
The system does not operate at start.
"[Da.1] Operation pattern" is "Continuous path control"
when "[Da.2] Control method" is "Speed control",
"Fixed-feed", "Position-speed switching control" or
"Speed-position switching control".
[Operation status at error occurrence]
The system does not operate at start.
The operation pattern set value is 2.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/sudden stop) of the detailed
parameter 2 Sudden stop selection (stop group 3).
(Note that the deceleration stop only occurs during the
manual pulse generator operation.)
Remedy
At operation start, during operation: Correct the "[Da.6]
Positioning address/movement amount".
At operation start: Set the current feed value within the
software stroke limit by the manual control operation.
At operation start, during operation: Correct the "[Da.6]
Positioning address/movement amount" and the
"[Da.7] Arc address".
At operation start: Set the current feed value within the
software stroke limit by the manual control operation.
• Do not designate a current value changing using the
positioning data following the continuous path
control.
• Do not designate positioning data following
continuous path control using a "current value
changing".
• Do not designate a current value changing using the
positioning data following the continuous path
control.
• Do not designate positioning data following
continuous path control using a "current value
changing".
Correct the "[Da.1] Operation pattern" or "[Da.2]
Control method".
Correct the "[Da.1] Operation pattern" or "[Da.2]
Control method".
Correct the "[Da.1] Operation pattern" or "[Da.2]
Control method".
Correct the operation pattern.
